我正在尝试使用Jerry我的 java 项目中来自 Jodd 的模块，我下载了该模块 jodd-lagarto- 3.4.5 jar 并添加到类路径中。我开始编写如下代码。
public void testJerryParserCreation() {
Jerry.JerryParser jerryParser = Jerry.jerry();
((LagartoDOMBuilder) jerryParser.getDOMBuilder()).enableXmlMode();
Jerry doc = jerryParser.parse("<xml> <book isbn='123'> <name>Foo<br></name> </book></xml>");
Jerry name = doc.$("book name");
assertEquals("Foo", name.text());
assertEquals("<xml><book isbn=\"123\"><name>Foo<br></br></name></book></xml>", doc.html());
}
但是在上面的第一行测试中，它给出了以下异常。这里可能出了什么问题。我的 jar 不正确吗？

最佳答案
很简单:) jodd-lagarto 模块依赖于 jodd-core 模块，该模块缺少类(以及 Lagarto 正在使用的其他实用程序)。检查download page查看所有模块和依赖项。对于您的版本，可能还依赖于 slf4j 记录器(最近已删除)。
您还可以考虑使用一些依赖管理工具，例如gradle或maven。所有依赖项都会自动下载。
如果可能的话，尝试使用最新版本的Jodd:)目前是3.4.10； 3.5快出来了。新版本包含一些与 Lagarto 相关的重要改进、修复和性能提升:) 尽情享受!
